To a'ZZ whom, it may concern.-

Be it Known that I, CnARLnsJ. KINTNER, a citizen of the United States, residing in New York, borough of Manhattan, county lating and State of New York, have made anew and useful Invention in Syringes, of which the following is a specification.

My invention is directed particularly to an improvement in syringes of the fountain type; and it has for its objects, first, to pro vide a novel form of tubular syringe adapted for use either with the faucet or faucets of a washbasin or bath-tub or other stationary water-supply or with open-mouthed or opentop vessels-such as washbasins, pitchers, or the like-upon. the siphon principle; second, to devise a novel type of vent for use in connection with the syringe when used with the faucets of a stationary source of water-supply; third, to devise a novel type of nozzle such that it embraces at one and the same time not only an absolute cut-off, but means for regulating the flow of water therethrough.

in a prior United States patent granted to me on the 3d of Qctober, 1905, and numbered 801,019, I have described and claimed generically flexible or yielding means for connecting a flexible or tubular syringe with the faucet of a washhasin or a bath-tub and venting means connected therewith for regu the flow of water to a syringe-nozzle,

and therefore make no claim in the present case to the application of this-generic ventmg principle,'the particular feature of vent ing, in so far as it refers to the present case, bein an improvement upon that disclosed in the efore-mentioned patent. In said patcut I have also-disclosed the usual type of spring or snap cut-off, combined with a soft flexible rubber s rin s-tube such tubes it is well known, becoming seriously damaged if such flexible snap cut-ofi's be left closed for an-indefinit'e length of time. It was with the object, therefore, of overcoming this objection that a second feature of my invention was devised-namely, the production of a telescoping nozzle which constitutes at one I and the same time not only an absolute cutoff which will not damage or in any sense efiect the condition of the tube, but also a means of regulating the flow at the eduction-' holes of the nozzle, as desired.

For a full and clear understanding of my invention, such as will enable others skilled all of which like numerals Figure 1 represents a sectional view taken througha stationary washbasin with the faucets lllustrated in elevational view and my novel form of syringe as attachedthereto,

the dotted lines illustrating the same when utilized upon the siphon principle. Fig. 2 is an enlarged sectional view taken through the flexible or yielding connector, the induction end of the syringe-tube, and the novel ventingconnector. Fig. 3 is a longitudinal sectional view taken through one form of my novel syringe-nozzle, the end of the syringe-tube being shown in side elevational view. Fig. 4 is an end elevational view of the connector shown in Fig. left to right. Fi s. 5 and 6 arejlon itudinal sectional views 0 modified forms of the im- Iproved nozzle shown as connected to the ee end of a syringe-tube.

Referring now to the drawings in detail, in represent like parts wherever used, 1 represents a flexible syringetube of the usual type, preferably of soft rubher, and 2 a well-known form of fiexible connector for connecting the same directly to one of the faucets of a washbasin, said basin being shown insectional view and as partly filled with water.

3 (see Fig. 3) represents one form of my novel type of syringe-nozzle, the same being constructed either of hard rubber or of metal, such as silver, or other metal heavily electroplated, said nozzle having the conformation shown with a rib 7 at .its inner end and a lon- .gitudinal interior opening of the same diameter as the exterior diameter of the syringetube 1, I

8 8 8 are the eduction-holes, and 9 is a con-- ical-shaped, projection at the inside of the outer end adapted to fit within the-inner end of the tube 1 when the latter is 1 ressed firmly home,vso as to thereby cut off he entire'supply of Water from the eduction-holes 8 8 8. v In Figs. 2 and 4 I have shown a novel ventin'g-connector 4, which is of tubular form and made, preferably, of very hard glass or metaland provided with radially-disposed arms 5, as shown, so arranged with relation to each other as to constitute openings 6 for the outflow of water around the connected end of the siphon-tube 1. This form of the invention is used as follows, the partsbeing put to:

2 as seen lookingthereat from user then forces the nozzle 3 backward over the end of the tube 1, so that the entire flow of water through. the eductio n-holes '8 is out off. All of the water then flows through the vent-openings 6 into the basin in the same manner as pointed out in the before-named patent. The syringe is then ready for use, and the flow may be regulated by adjusting the nozzle 3 upon the end of the tube 1, so as to expose more or less of the eduction-holes 8. In this form of the invention the rubber tube 1 should be of sufficient hardness to readily permit of its bein inserted freely into and withdrawn from t e nozzle 3, and for this purpose, if preferred, the free or outer end of said tube maybe vulcanized to a point of relativellfy much greater hardness than the tube itse In the modified form of the nozzle shown in Fig. 5 said nozzle is composed of two telescoping parts 3 and 10, the part 10 being of hard rubber or metal and rovided with the usual outer connecting on for securing it. to the free end of the siphon-tube 1, this form of the nozzle being the preferred one, for the reason that it is not always possible with the soft-rubber tube and hard-rubber nozzle 3 to obtain the best possible results, altho ugh reasonably good action is had.

With the form shown in Fig. 5 an accurate adjustment may be had between the two telescoping parts 3 and 10, such that the user may move it to any desired point, and with such an arrangement also I am enabled to pack the nozzle in smaller space, as the telescoping parts when in use are withdrawn, so as to increase the length of the nozzle. i In Fig. 6 I have shown a still further modi- -fied form of the nozzle in which the outer shell 3 is composed of two parts screwthreaded together, and the inner telescoping partlOfits accurately therein after the manner of a iston within said outer'shell, the o eration eing obvious on inspe'ctioh of t e drawings; With this form of the invention there islittle dan er of; losing the two parts b reason of theirieeomin separated. It is o vious that instead'of e ecting the opera 1 tion'of cutting off the flow through theeduo- -tion-holes b thetelescopic action of the two parts 3 an 10 moving: longitudinally "the same 'might be efieeted'by' rotary movement, both tubes being provided with openseems in s or the inner tube with slots-.longitudii na ly arranged, such a modified form being obviousl within the scope of my invention. If it be desired to use the invention upon the principle of a siphon, it only becomes neces- 7 sary to coil the entire tube within the body of the basin when the sameis'full'of Water, having first removed the nozzle 3' from the outer end of the tube.

After all the airrbubbles have been forced '1 out of the immersed tube, and hence the iatter is full of water, the nozzle isforced'firmly home, so as to out off all supply of air, and the tube is then quickly withdrawn from the basin and the weight of the connector 2' and the metal or glass venting-connectors is-s'ufficient -to retain the short leg of the siphon within the basin, the long is having been withdrawn to a point where t e nozzle isto be used and below the level of the water in the basin. Ofcourse this use of the invention may be applied with a basin, bueizet, or

other operi-mouthed vessel, and I inakeno' claim hereinafter to this feature, as the same .constitutes the subject-matter of 'still'van g other application filed by me on the ZZdJ'day of July and bearing serial number 210,881.

I do not limit. my invention to the especial said inner connectin part being closed at its inner end and provi ed with a cut-off hole 0e.- opening near its longitudinal centeiy ithe 1 eduction-hole being at the other end'of:-the nozzle, which is attached directly tolthe inner telescoping part, the arrangement being such that when said telescoping-parts are extended the flow of water'is suspended; as I disclosed in German Patent No. 60,877, 0f

August 18, 1891,-and I make no claim hereim.

after broad enough to include such a device, the limiting feature of my claims in-frelatfion to my improved nozzle being to the'utiliza-- tion of the eduction-holes themselves when combined with a telescoping sleeve on part whereby said eduction-holes may be either wholly or partially-closed as desiredbyithe' telescoping action of the parts. i 1

Having thus described my invention, what I claim, and desire to secure by LettersvPah ent of the United States, is-

1. In a syringe of the fountain type a-faucot-connector, a flexible tube and a venting- I connector provided with radiallydisposed vent-openings for permitting of the passage of water between the faucet-connector'and the end oi' the tube, substantiallyasdlescr'ibed; 1

2. In a syringe of the fountain type a fanset-connector, a flexible tube, a nozzle, and a venting-connector for connecting the flexible tube to the faucet-connector, theweight of the faucet and venting connectors being sufficient to hold or secure the short leg of the tube within a basin or stationary supply of water when used upon the siphon principle, substantially as described.

3. A syringe of the fountain type embracing a faucet-connector, a flexible tube, a venting-connector for connecting the latter to'the faucet-connector, and a nozzle, substantially as described. Y i

4. A syringe of the fountain type embracing a faucet-connector, a flexible tube, a venting-connector for connecting the tube to the faucet-connector, and a two-part telescoping nozzle, one of said telescoping parts being provided with eduction-holes or openings, and the other. adapted to cut off the flow of water therethrough, substantially as described.

5. A syringe-nozzle embracing two tele scoping parts, one of which is provided with eduction holes or openings at its free end and both of which combined are adapted to out off all the flow of water through the eduction-holes by sliding one over the other and I over said eduction-holes, substantially as described. v

6. A syringe-nozzle embracing two telescoping parts, one of which is provided with two or more sets of eduction-holes arranged -1n groups near its free or outer end, said tele-v scoping parts having movement the one over the other and over said eduction-holes, and

in such manner that either a part or all of the flow of water through the eduction-holes may be cut oif, substantially as described.

7. A syringe-nozzle embracing two telescoping parts and a series of eduction holes or openings, the outer part being provided with a conical-shaped projection adapted to fit within the free end of the inner part in such manner as to absolutely close the flow of water to the eduction-holes, substantially as described.

8. A syringe-nozzle embracing two telescoping parts adjustable in the direction of their length and a series of eduction-holes radially disposed near the end of the outer part, the arrangement being such that when the two parts are fully telescoped the eduction-holes are all closed and the supply of water out off, and when withdrawn the number of holes left open is regulated to suit the convenienceof the user, substantially as described.

9. Means for utilizing water flowing from faucets, consisting of a flexible faucet-connector, a flexible tube and a venting-connector adapted to connect the faucet-connector and the flexible tube together, substantially as described.
